[QUOTE="MrSpectrum, post: 1924728, member: 105703"] [color=#008000]This is incorrect[/color]; my meter was pointed vertically (straight up) for all readings. I took readings the way I did because my dragon does not bask in one dimension; he basks in 2 dimensions (well, 3 actually), moving where he chooses--for both warmth and UVB--atop his 16" x 8" platform. At very rare times, he'll bask on a 4" x 8" step 2.5" below and directly left of the main platform. I have not taken readings on that step. In subsequent readings along the left and right sides of the platform, I was able to determine that any increase in UVI was only [i]directly [/i]under the centerline of the bulb. Any increase dropped substantially as soon as the meter was moved as little as one inch off of that centerline, and dropped off entirely at approx. 2" in either direction off centerline. IOW, the area of increase from reflection was limited to the footprint of the reflector. Beyond that, there is no increase. In attempting to determine why my reflector kinked and shattered upon attempting to flip it, I learned that mylar comes in different formulations. While mylar [i]can [/i]be formulated to be UV resistant, it is more expensive to mfr. and mfrs. will only do it in large special orders. Unless specified to be UV resistant, mylar will break down (becoming brittle) with exposure. I can only speculate: I don't know what type of mylar Sunblaster specifies for their reflectors, or if a substitution may have been made at the factory. My guess is that they didn't expect reflectors to be flipped (or need to be) so becoming brittle may not have been a concern. If installed properly initially, the aluminum coating may have blocked and negated deleterious effects of UV eposure. Since my reflector was so brittle, I can only surrnise that the UV of the bulb caused the mylar to break down due to the reflector being installed incorrectly at the factory. [/QUOTE]
